Recombinant Human S100A8-S100A9 Protein，His

S100A8-S100A9

S100A8 consists of calcium and zinc bound S100A8, which plays a critical regulatory role in inflammation and immune responses. As calprotectin, it contributes to leukocyte function, regulates the cytoskeleton, and activates intracellular NADPH oxidase. S100A8-S100A9 Heterodimer Protein, Human (His, solution) is a recombinant protein dimer complex containing human-derived S100A8-S100A9 Heterodimer protein, expressed by E. coli , with C-6*His labeled tag.

The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.
